Figure 3. — Cardiac magnetic resonance parameters for the study groups. LV ejection fraction (A). LV end-diastolic volume index (B), LV mass index (C), magnetic resonance spectroscopy–derived PCr/ATP ratio (D), CK k_f (E), and forward CK flux (F) in nonhypertrophied, non–pressure-loaded healthy volunteer hearts (NHv),in non–pressure-loaded hearts with normal LVEF undergoing LV biopsy (NHBx), and in hearts with moderate AS (Mod-AS), SevAS with preserved (SevASpEF) and reduced (SevASrEF) ejection fraction. For between-group comparison, *P<0.05, **P<0.01, ***P<0.001; otherwise P>0.05. AS indicates aortic stenosis; CK, creatine kinase; LVEDVi, indexed left ventricular end-diastolic volume; LVEF, left ventricular ejection fraction; LV, left ventricular; LVMi, left ventricular mass index; and PCr, phosphocreatine.
